.SH DESCRIPTION
.IR Getfsent ,
.IR getfsspec ,
and
.I getfsfile
each return a pointer to an object with the following structure
containing the broken-out fields of a line in the file system
description file,
.IR < fstab.h >.

.PP
.nf
struct fstab {
	char	*fs_spec;
	char	*fs_file;
	char	*fs_type;
	int	fs_freq;
	int	fs_passno;
};

The fields have meanings described in
.IR fstab (5).

.I Getfsent
reads the next line of the file, opening the file if necessary.
.PP
.I Setfsent
opens the file, or rewinds it if it is already open.
.PP
.I Endfsent
closes the file.
.PP
.I Getfsspec
and
.I getfsfile
sequentially search from the beginning of the file until a matching
special file name or file system file name is found, or until EOF is
encountered.
.PP
Entries in the file with a type field equivalent to \fIFSTAB_XX\fP
are ignored.
